libceph: osd_request_timeout option
osd_request_timeout specifies how many seconds to wait for a response
from OSDs before returning -ETIMEDOUT from an OSD request. 0 (default)
means no limit.
osd_request_timeout is osdkeepalive-precise -- in-flight requests are
swept through every osdkeepalive seconds. With ack vs commit behaviour
gone, abort_request() is really simple.
This is based on a patch from Artur Molchanov <artur.molchanov@synesis.ru>.
